Location determination systems, such as the global positioning system (GPS), have provided the ability to identify and track locations and movement of devices. Although fairly accurate outdoors, many location determination systems cannot detect when a device is indoors. Solutions have been proposed for locating devices indoors involving beacons, transponders, and/powerlines. However, these systems can only locate the devices themselves rather than other objects within the system. Furthermore, these system serve no other purpose than to track devices.

I. Wireless Charging System Overview/Architecture
As shown in the example of
Each charger 101 (also referred to herein as a “transmitter”, “array of antennas” or “antenna array system”) can include multiple antennas 104, e.g., an antenna array including hundreds or thousands of antennas, which are capable of delivering wireless power to wireless devices 102. In some embodiments, the antennas are adaptively-phased radio frequency antennas. The charger 101 is capable of determining the appropriate phases to deliver a coherent power transmission signal to the power receiver clients 103. The array is configured to emit a signal (e.g., continuous wave or pulsed power transmission signal) from multiple antennas at a specific phase relative to each other. It is appreciated that use of the term “array” does not necessarily limit the antenna array to any specific array structure. That is, the antenna array does not need to be structured in a specific “array” form or geometry. Furthermore, as used herein he term “array” or “array system” may be used include related and peripheral circuitry for signal generation, reception and transmission, such as radios, digital logic and modems. In some embodiments, the charger 101 can have an embedded Wi-Fi hub.
The wireless devices 102 can include one or more receive power clients 103. As illustrated in the example of
Each power receiver client 103.1-103.n includes one or more antennas (not shown) for receiving signals from the chargers 101. Likewise, each charger 101.a-101.n includes an antenna array having one or more antennas and/or sets of antennas capable of emitting continuous wave signals at specific phases relative to each other. As discussed above, each array is capable of determining the appropriate phases for delivering coherent signals to the power receiver clients 102.1-102.n. For example, coherent signals can be determined by computing the complex conjugate of a received beacon signal at each antenna of the array such that the coherent signal is properly phased for the particular power receiver client that transmitted the beacon signal.
Although not illustrated, each component of the environment, e.g., wireless power receiver, charger, etc., can include control and synchronization mechanisms, e.g., a data communication synchronization module. The chargers 101.a-101.n can be connected to a power source such as, for example, a power outlet or source connecting the chargers to a standard or primary alternating current (AC) power supply in a building. Alternatively or additionally, one or more of the chargers 101.a-101.n can be powered by a battery or via other mechanisms.
In some embodiments, the power receiver clients 102.1-102.n and/or the chargers 101.a-101.n utilize reflective objects 106 such as, for example, walls or other RF reflective obstructions within range to beacon and deliver and/or receive wireless power and/or data within the wireless power delivery environment. The reflective objects 106 can be utilized for multi-directional signal communication regardless of whether a blocking object is in the line of sight between the charger and the power receiver client.
As described herein, each wireless device 102.1-102.n can be any system and/or device, and/or any combination of devices/systems that can establish a connection with another device, a server and/or other systems within the example environment 100. In some embodiments, the wireless devices 102.1-102.n include displays or other output functionalities to present data to a user and/or input functionalities to receive data from the user. By way of example, a wireless device 102 can be, but is not limited to, a video game controller, a server desktop, a desktop computer, a computer cluster, a mobile computing device such as a notebook, a laptop computer, a handheld computer, a mobile phone, a smart phone, a PDA, a Blackberry device, a Treo, and/or an iPhone, etc. The wireless device 102 can also be any wearable device such as watches, necklaces, rings or even devices embedded on or within the customer. Other examples of a wireless device 102 include, but are not limited to, safety sensors (e.g., fire or carbon monoxide), electric toothbrushes, electronic door lock/handles, electric light switch controller, electric shavers, etc.
Although not illustrated in the example of
Additionally, in some embodiments the beacon signal, which is primarily referred to herein as a continuous waveform, can alternatively or additionally take the form of a modulated signal.
In some embodiments, the charger 101 includes many antennas; one or more of which are used to deliver power to the power receiver client 103. The charger 101 can detect phases at which the beacon signals that are received at each antenna. The large number of antennas may result in different beacon signals being received at each antenna of the charger 101. The charger may then determine the complex conjugate of the beacon signals received at each antenna. Using the complex conjugates, one or more antenna may emit a signal that takes into account the effects of the large number of antennas in the charger 101. In other words, the charger 101 emits a signal from one or more antennas in such a way as to create an aggregate signal from the one or more of the antennas that approximately recreates the waveform of the beacon in the opposite direction.
As described herein, wireless power can be delivered in power cycles. A more detailed example of the signaling required to commence wireless power delivery is described below with reference to
In an example of operation, a master bus controller (MBC), which controls the charger array, receives power from a power source and is activated. The MBC activates the proxy antenna elements on the charger array and the proxy antenna elements enter a default “discovery” mode to identify available wireless receiver clients within range of the charger array. When a client is found, the antenna elements on the charger array power on, enumerate, and (optionally) calibrate.
Next, the MBC generates a Beacon Beat Schedule (BBS) cycle, and a Power Schedule (PS) for all wireless power receiver clients that are to receive power based on their corresponding properties and/or requirements. The MBC also identifies any other available clients that will have their status queried in the Client Query Table (CQT). Clients that are placed in the CQT are those on “standby”, e.g., not receiving a charge. The BBS and PS are calculated based on vital information about the clients such as, for example, battery status, current activity/usage, how much longer it has until it runs out of power, priority in terms of usage, etc.
The Proxy AE broadcasts the BBS to all clients. As discussed herein, the BBS indicates when each client should send a beacon. Likewise the PS indicates when and to which clients the array should send power to. Each client starts broadcasting its beacon and receiving power from the array per the BBS and PS. The Proxy can concurrently query the Client Query Table to check the status of other available clients. A client can only exist in the BBS or the CQT (e.g., waitlist), but not in both. In some embodiments, a limited number of clients can be served on the BBS and PS (e.g., 32). Likewise, the CQT may also be limited to a number of clients (e.g., 32). Thus, for example, if more than 64 clients are within range of the charger, some of those clients would not be active in either the BBS or CQT. The information collected in the previous step continuously and/or periodically updates the BBS cycle and/or the PS.
The control logic 310 is configured to provide all control and intelligence to the array components. The control logic 310 may comprise one or more processors, FPGAs, memory units, etc., and direct and control the various data and power communications. The communication block 330 can direct data communications on a data carrier frequency, such as the base signal clock for clock synchronization. The data communications can be Bluetooth, Wi-Fi, Zigbee, etc. Likewise, the proxy 340 can communicate with clients via data communications as discussed herein. The data communications can be Bluetooth, Wi-Fi, Zigbee, etc. The external power interface 320 is configured to receive external power and provide the power to various components. In some embodiments, the external power interface 320 may be configured to receive a standard external 24 Volt power supply. Alternative configurations are also possible.
A combiner 455 receives and combines the received power transmission signals from the power transmitter in the event that the receiver 400 has more than one antenna. The combiner can be any combiner or divider circuit that is configured to achieve isolation between the output ports while maintaining a matched condition. For example, the combiner 455 can be a Wilkinson Power Divider circuit.
The rectifier 450 receives the combined power transmission signal from the combiner 455, if present, which is fed through the power meter 440 to the battery 420 for charging. The power meter 440 measures the received power signal strength and provides the control logic 410 with this measurement. The control logic 410 also may receive the battery power level from the battery 420 itself. The control logic 410 may also transmit/receive via the communication block 430 a data signal on a data carrier frequency, such as the base signal clock for clock synchronization. The beacon signal generator 460 transmits the beacon signal, or calibration signal, using either the antenna 480 or 490. It may be noted that, although the battery 420 is shown for being charged and for providing power to the receiver 400, the receiver may also receive its power directly from the rectifier 450. This may be in addition to the rectifier 450 providing charging current to the battery 420, or in lieu of providing charging. Also, it may be noted that the use of multiple antennas is one example of implementation and the structure may be reduced to one shared antenna.
A client identifier (ID) module 415 stores a client ID that can uniquely identify the power receiver client in a wireless power delivery environment. For example, the ID can be transmitted to one or more chargers when communication are established. In some embodiments, power receiver clients may also be able to receive and identify other power receiver clients in a wireless power delivery environment based on the client ID.
An optional motion sensor 495 can detect motion and signal the control logic 410 to act accordingly. For example, when a device is receiving power at high frequencies, e.g., above 500 MHz, its location may become a hotspot of (incoming) radiation. Thus, when the device is on a person, e.g., embedded in a mobile device, the level of radiation may exceed acceptable radiation levels set by the Federal Communications Commission (FCC) or other medical/industrial authorities. To avoid any potential radiation issue, the device may integrate motion detection mechanisms such as accelerometers or equivalent mechanisms. Once the device detects that it is in motion, it may be assumed that it is being handled by a user, and would trigger a signal to the array either to stop transmitting power to it, or to lower the received power to an acceptable fraction of the power. In cases where the device is used in a moving environment like a car, train or plane, the power might only be transmitted intermittently or at a reduced level unless the device is close to losing all available power.
II. Imaging and Tracking Objects/Heat and Flow Map Generation
Various techniques and examples for imaging wireless power delivery environments and tracking objects contained therein are described in more detail below. More specifically, the embodiments below describe techniques for generating a 3D image (or hologram) of the wireless power delivery environment including static or semi-static objects using beacon signaling transmitted by power receiver clients distributed throughout the environment. The techniques also describe tracking non-static objects through the wireless power delivery environment and generating heat and flow maps to indicate movement of the non-static objects within the environment.
As illustrated in the example of
In some embodiments, the charger 501 communicates with the processing system 550 via any wired or wireless network. Furthermore, although shown as distinct systems, in some embodiments some or all of the components and/or functionality of the processing system 550 can, alternatively or additionally, be included in one or more wireless chargers 501.
As shown in the example of
As discussed herein, the wireless charger 501 is configured with multiple adaptively-phased antennas that receive beacon signals from the power receiver clients 503a-503n and measure the phases of the beacon signals at each of multiple adaptively-phased antennas. In some embodiments, the magnitudes of the beacon signals are also measured and compared as described herein. As illustrated in
During the learning (or training) phase, the 3D image (or hologram) of the wireless power delivery environment is generated based on received phases. The period of time t1 that is necessary to generate an initial 3D image (or hologram) of the wireless power delivery environment can vary depending on a number of factors. For example, the complexity of the environment, the number of chargers, the number of wireless power receivers transmitting beacon, and movement of non-static objects can all have an impact on the time that is required to generate an initial 3D image (or hologram) of the wireless power delivery environment.
In some embodiments, the wireless charger 501 sends the phase measurements to the processing system 550 which receives the signals and, over a period of time, identifies the environment. For example, the processing system 550 can average the measurements over time to get a view of an empty store with static objects, e.g., by subtracting any objects that move. An example process for generating a 3D image (or hologram) of the wireless power delivery environment is shown and discussed in greater detail with reference to
During the tracking and updated phase, non-static objects are tracked though the 3D image (or hologram) of the wireless power delivery environment e.g., a retail environment. For example, non-static or moving objects such as, for example, customers in a retail environment can be tracked through the wireless power delivery environment e.g., a retail environment based on phase changes measured in the received beacon signals. An example process of tracking objects in a wireless power delivery environment is shown and discussed in greater detail with reference to
To begin, at process 710, the wireless power delivery system sequentially receives beacon signals from multiple power receiver clients respectively in a wireless power delivery environment. As discussed above, the power receiver clients can transmit beacons according to a BBS. At process 712, the wireless power delivery system measures the phase of the beacon signals at each of multiple adaptively-phased antennas. At process 714, the wireless power delivery system generates a phase pattern for each received beacon signal. The phase pattern includes the phase of the beacon signal as measured at each of the multiple adaptively-phased antennas.
At process 716, the wireless power delivery system compares each phase pattern generated for a beacon signal sent from a power receiver client to a previous phase pattern generated for a beacon signal sent from the power receiver client to identify phase differences. At decision process 718, the wireless power delivery system determines if the phases are differ over time. The process is performed by averaging out the measurements over a period of time to obtain a view of the environment with only static or semi-static objects. Non-static (or moving) objects are removed and/or otherwise subtracted out. If the measured phases substantially differ over time then the wireless charging system returns to process 710. If the measured phases are substantially the same over time then, at process 720, the wireless charging system saves the expected phase pattern for the beacon signal. As discussed herein, the phase pattern can include the expected phase of the beacon signal at each of the multiple adaptively-phased antennas.
At decision process 730, the wireless power delivery system determines if the expected phase patterns for more than a threshold of the power receiver clients have been saved. In some embodiments, the threshold can be include expected phase patterns for all of the power receiver clients in the wireless power delivery environment. Alternatively, the threshold can be a fraction or percentage of the beacons received from all power receiver clients within range.
At process 732, the wireless power delivery system processes the expected phase patterns in aggregate to identify static or semi-static objects and other obstructions within the wireless power delivery environment. In some embodiments, ultrasound mathematics can be used to identify the static or semi-static objects and the other obstructions within the wireless power delivery environment.
Lastly, at process 734, the wireless power delivery system generates a 3D image (or hologram) of the wireless power delivery environment include the static or semi-static objects and the other obstructions. As discussed herein, static or semi-static objects can be any objects that do not move for a movement threshold, e.g., multiple minutes, hours, days, etc. For example, shelfing units in a retail store or even items on the shelfs can be considered static or semi-static even though they may eventually be moved or sold. Non-static items are those objects that exceed the movement threshold. For example, customers or patrons may move about a store and remain static for short periods of time without exceeding the movement threshold, e.g., while waiting in line, reading product information, etc., are thus, considered non-static objects herein.
To begin, at process 810, the wireless power delivery system receives beacon signals transmitted by multiple power receiver clients in the wireless power delivery environment. As discussed herein, the beacon signals are received at multiple adaptively-phased radio frequency antennas of the wireless power delivery system over a period of time.
At process 812, the wireless power delivery system generates a phase pattern for each received beacon signal. Each phase pattern includes a measured phase of the received beacon at each of the multiple adaptively-phased RF antennas. In some embodiments, the phase pattern can also include measured magnitude information of the received beacon signal at each of the multiple adaptively-phased RF antennas.
At process 814, the wireless power delivery system compares the phase patterns to an expected phase pattern. As discussed herein, the expected phase pattern includes the phases at which each beacon signal is expected to be received by the wireless power delivery system in the absence of non-static (or moving) objects within the wireless power delivery environment, which can affect the measured phases.
At process 816, the wireless power delivery system processes the phase differences to identify one or more non-static objects within the wireless power delivery environment.
At process 818, the wireless power delivery system tracks movement data associated with the one or more non-static objects based on the 3D image (or hologram) of the wireless power delivery environment and the phase differences in the phase patterns. For example, in some embodiments, ultrasound mathematics can be used to identify and track the locations or movement of the non-static objects within the wireless power delivery environment. As discussed above, the three-dimensional image identifies shapes and relative locations of static or semi-static objects within the wireless power delivery environment. In some embodiments, the shape and relative locations of the static and non-static objects in the wireless power delivery environment can be determined with wavelength level accuracy.
At process 820, the wireless power delivery system aggregates the movement data associated with the one or more non-static objects within the wireless power delivery environment. In some embodiments, the movement data can be aggregated over a period of time, e.g., 2 hour time periods, a day, etc.
At process 822, the wireless power delivery system generates a motion-based map indicating the aggregated movement of the one or more non-static objects within the wireless power delivery environment.
In some embodiments, generating the motion-based map includes processing the aggregated movement data associated with the one or more non-static objects to identify one or more dwell points within the wireless power delivery environment, and identifying the dwell points on the three-dimensional image of the wireless power delivery environment. The dwell points can indicate stagnation in particular area of the wireless power delivery environment for a corresponding dwell time. The identification of the dwell points on the three-dimensional image can include, for example, superimposing or otherwise marking the dwell points on the three-dimensional image of the wireless power delivery environment. Alternatively or additionally, the dwell points could be added on top of the three-dimensional image of the wireless power delivery environment via layer data. Other examples are also possible.
In some embodiments, the dwell points indicate a corresponding dwell time on the three-dimensional image of the wireless environment. Colors or shading can be used to indicate the dwell time. For example, darker shading or colors could indicate a longer dwell time. In some instances, the system can determine the shade or color based on pre-determined ranges of time or quantization. An example motion-based map that includes the dwell times (also referred to as a heat map herein) is shown in
In some embodiments, generating the motion-based map includes processing the aggregated movement data associated with the one or more non-static objects to identify one or more motion vectors within the wireless power delivery environment, and identifying the motion vectors on the three-dimensional image of the wireless power delivery environment. The motion vectors can indicate a general direction of motion of the one or more static objects and can be, in some embodiments, derived from the motion-based map including the dwell times. The identification of the motion vectors on the three-dimensional image can include, for example, superimposing or otherwise marking the motion vectors on the three-dimensional image of the wireless power delivery environment. Alternatively or additionally, the motion vectors could be added on top of the three-dimensional image of the wireless power delivery environment via layer data. Other examples are also possible. The motion vectors can be derived from movement data and in some instances, indicate a magnitude of the flow. For example if most customers move in a particular direction, e.g., >90%, the motion vector can be darkened or lengthened relative to other vectors.
III. Retail Solutions and Wireless Electronic Displays

The wireless devices can be wireless devices 102.1-102.n of
Objects within the retailer power distribution premises 920 can subsequently be tracked based on phase changes in received beacon signals that are measured at the wireless chargers 901. As discussed herein, the phase changes occur as a result of non-static objects or obstructions, e.g., customers moving around a store, etc. The phase changes are used in conjunction with the 3D image (or hologram) of the environment to determine relative locations of objects and to track objects (e.g., customers) through the retailer power distribution premises 920. In some instances, customers can also be individually identified and tracked via wireless power receiver client embedded on their person, e.g., in their wireless device, or embedded in a cart or basket associated with the customer.
As discussed herein, techniques are also described for determining customer behavior or patterns. In the example of
In some embodiments, the electronic displays (e.g., price tags) described in this example are wirelessly charged and thus, retailers can drive price changes without being concerned with the draining batteries or battery systems of the electronic displays. In some embodiments, each wirelessly-powered electronic display can represent a mini e-Commerce website for the specific item. The electronic display can present data including information associated with an item or product.

Customer profile information such as customer preferences, purchase history, etc., can be maintained and/or otherwise processed in various locations. For example, the retailer may maintain customer profile information at a central retailer system 915 in one or more databases 910. This can be useful for retailers with multiple store locations. Alternatively or additionally, local systems such as, for example, retailer system 970 can maintain customer profile information. In some embodiments, the information is provided to various local retailer systems 970 by a central retailer system 915.
As discussed herein, the electronic display(s) 980a-n can receive power and/or data from wireless chargers 901. Alternatively or additionally, the electronic display(s) 980 can have other wired or wireless networking connections and/or otherwise be in communication with a local retailer system 970 and/or a central retailer system 915. For example, the electronic display(s) 980 can be in communication with a local retailer system 970 and/or a central retailer system 915 via a wireless local area network (WLAN) such as Wi-Fi, Wi-Fi Direct, etc., or a wireless personal area network (WPAN) such as Bluetooth, Zigbee, RFID etc. In some embodiments, the electronic display(s) 980 and/or the local retailer system 970 and/or the central retailer system 915 can also be in direct communication with customers' wireless devices via WLAN, WPAN, etc.
In some embodiments, the retailer systems can dynamically push out price updates for items or products to the electronic display(s) 980. The price update information can be pushed out to the electronic display(s) 980 by way of one or more chargers 2301. Alternatively or additionally, the price update information can be pushed out wirelessly to the electronic display(s) 980 via a local retailer system 970 and/or a central retailer system 915. The system can also track item or product availability for product ordering (reordering), shelf restocking, etc.
In some embodiments, the electronic display(s) 980 comprise price information, e.g., electronic price tags. Once the customer is within a specific range (threshold range) from the electronic price tag, the electronic price tag may be able to identify the customer through, for example, a loyalty card or the customer's wireless device. As discussed herein, profile information can be kept and stored about customers in addition to tracking the customers. The electronic displays 980, e.g., electronic price tags, can then customize information to the customer. As discussed in greater detail below, the electronic displays have embedded power receiver clients that send beacon signals to a charger and are used to generate a map of the wireless environment. In some embodiments, the retailer systems may know the layout of the store and communicate with the charger the locations of the static electronic displays through wired or wireless mechanisms.
In some embodiments, the cloud processing system 950 can process information related to items purchased by customers at one or more retailer locations, items purchased by similar customers, etc., and provide product recommendations and/or messages to the customers. The product recommendations and/or messages can be provided to the customer's associated wireless device and/or display equipped cart/basket. Alternatively or additionally, the product recommendations and/or messages can be provided to the electronic displays 980 near or proximate to the customer. In yet other embodiments, the product recommendations and/or messages can be sent to the customers via email, SMS messaging, etc.
As discussed above, the techniques described herein can facilitate various data collection, customer tracking, and motion detection functionality. The collected data can be processed by a cloud processing system to develop individual profile information about customers and/or aggregated and provided to third party data consumers 910. The profile information can include historical data, e.g., purchases, visits, movement through retail premises, etc.
In some embodiments, the system provides for various consumer reviews including descriptions and rankings (or scoring) of products. Examples of a customer scoring and a customer description review are shown and discussed in greater detail with reference to
In some embodiments, a customer can create a shopping list and use an application downloaded to the wireless device to automatically create a shopping plan route. The shopping plan route can be calculated based on the layout of the retail premises as determined by the charger. Furthermore, the wireless device can help guide the customer through the store in real-time and re-calculate the route automatically when the customer takes detours and/or otherwise changes course. Essentially, the system provides an indoor GPS system that tracks the customer through the retail environment using the customer's wireless device and/or cart/basket and the system's knowledge of the store layout, e.g., store shelving and electronic displays 980 for the particular items or products.
In some embodiments, one or more components of the system can direct the electronic displays to provide special instructions corresponding to an item purchased or to be purchased. The special instructions can, for example, include products and/or services that can be (or are regularly) used in conjunction and/or are otherwise related to a particular item purchased or to be purchased. The system can suggest the additional item and then guide the user through retailer premises to the location of the additional item.
As discussed above,
As illustrated in the example of
The power receiver client 1202 can be wireless power receiver client 400 of
The power harvesting module 1206 can harvest power received from a charger. The battery system 1210 can power operation of the electronic display 1202. The power receiver client 1202 can charge the battery system 1210 via an internal battery (not shown) or directly. As discussed, the Wi-Fi module 1220 and the Bluetooth (BT) module 1215 are configured to receive and process data communications from other systems or apparatuses within the wireless power delivery environment.
The memory 1235 can be any memory system configured to store instructions which can be executed by one or more controllers 1240. In some embodiments, the controllers can also control the display system 1230. In some embodiments, the display system 1230 can be an interactive system such as a touch screen display; however other embodiments are possible. By way of example and not limitation, the display screen 1230 can be an e-ink display, a liquid crystal display, a light emitting diode display, etc., including combinations or variations thereof.
In some embodiments, a payment module 1250 can process payment information and/or otherwise facilitate payment via the electronic display 1200. For example, a QR code generation module can generate a QR code that can be scanned by customer using a mobile device. Once scanned, cart information can be updated and payment can be made via the customer's mobile device. Alternatively or additionally, in some embodiments payment can be made via NFC module 1280. The information can be routed to the payment module 1250 for processing and finalization.
In some embodiments, the electronic display 1200 can identify proximate objects (e.g., customers) via a loyalty card, the user's mobile device, etc. For example, a loyalty card can have an embedded RFID tag which can be read by RFID module 1270 when proximate the loyalty card. The object identification module 1260 can search the database and/or otherwise request information about the use. Alternatively, the identity information can be transferred to a local or cloud-based retail or processing system for further processing.

The processor may be, for example, a conventional microprocessor such as an Intel Pentium microprocessor or Motorola power PC microprocessor. One of skill in the relevant art will recognize that the terms “machine-readable (storage) medium” or “computer-readable (storage) medium” include any type of device that is accessible by the processor.
The memory is coupled to the processor by, for example, a bus. The memory can include, by way of example but not limitation, random access memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM). The memory can be local, remote, or distributed.
The bus also couples the processor to the non-volatile memory and drive unit. The non-volatile memory is often a magnetic floppy or hard disk, a magnetic-optical disk, an optical disk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, a magnetic or optical card, or another form of storage for large amounts of data. Some of this data is often written, by a direct memory access process, into memory during execution of software in the computer 800. The non-volatile storage can be local, remote, or distributed. The non-volatile memory is optional because systems can be created with all applicable data available in memory. A typical computer system will usually include at least a processor, memory, and a device (e.g., a bus) coupling the memory to the processor.
Software is typically stored in the non-volatile memory and/or the drive unit. Indeed, for large programs, it may not even be possible to store the entire program in the memory. Nevertheless, it should be understood that for software to run, if necessary, it is moved to a computer readable location appropriate for processing, and for illustrative purposes, that location is referred to as the memory in this paper. Even when software is moved to the memory for execution, the processor will typically make use of hardware registers to store values associated with the software, and local cache that, ideally, serves to speed up execution. As used herein, a software program is assumed to be stored at any known or convenient location (from non-volatile storage to hardware registers) when the software program is referred to as “implemented in a computer-readable medium”. A processor is considered to be “configured to execute a program” when at least one value associated with the program is stored in a register readable by the processor.
The bus also couples the processor to the network interface device. The interface can include one or more of a modem or network interface. It will be appreciated that a modem or network interface can be considered to be part of the computer system. The interface can include an analog modem, isdn modem, cable modem, token ring interface, satellite transmission interface (e.g. “direct PC”), or other interfaces for coupling a computer system to other computer systems. The interface can include one or more input and/or output devices. The I/O devices can include, by way of example but not limitation, a keyboard, a mouse or other pointing device, disk drives, printers, a scanner, and other input and/or output devices, including a display device. The display device can include, by way of example but not limitation, a cathode ray tube (CRT), liquid crystal display (LCD), or some other applicable known or convenient display device. For simplicity, it is assumed that controllers of any devices not depicted in the example of
In operation, the computer system 1700 can be controlled by operating system software that includes a file management system, such as a disk operating system. One example of operating system software with associated file management system software is the family of operating systems known as Windows® from Microsoft Corporation of Redmond, Wash., and their associated file management systems. Another example of operating system software with its associated file management system software is the Linux operating system and its associated file management system. The file management system is typically stored in the non-volatile memory and/or drive unit and causes the processor to execute the various acts required by the operating system to input and output data and to store data in the memory, including storing files on the non-volatile memory and/or drive unit.
Some portions of the detailed description may be presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.
The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the methods of some embodiments. The required structure for a variety of these systems will appear from the description below. In addition, the techniques are not described with reference to any particular programming language, and various embodiments may thus be implemented using a variety of programming languages.
In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a client-server network environment or as a peer machine in a peer-to-peer (or distributed) network environment.
The machine may be a server computer, a client computer, a personal computer (PC), a tablet PC, a laptop computer, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, an iPhone, a Blackberry, a processor, a telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine.
While the machine-readable medium or machine-readable storage medium is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” and “machine-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” and “machine-readable storage medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the presently disclosed technique and innovation.
In general, the routines executed to implement the embodiments of the disclosure, may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processing units or processors in a computer, cause the computer to perform operations to execute elements involving the various aspects of the disclosure.
Moreover, while embodiments have been described in the context of fully functioning computers and computer systems, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms, and that the disclosure applies equally regardless of the particular type of machine or computer-readable media used to actually effect the distribution.
Further examples of machine-readable storage media, machine-readable media, or computer-readable (storage) media include but are not limited to recordable type media such as volatile and non-volatile memory devices, floppy and other removable disks, hard disk drives, optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks, (DVDs), etc.), among others, and transmission type media such as digital and analog communication links.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” As used herein, the terms “connected,” “coupled,” or any variant thereof, means any connection or coupling, either direct or indirect, between two or more elements; the coupling of connection between the elements can be physical, logical, or a combination thereof. Additionally, the words “herein,” “above,” “below,” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. Where the context permits, words in the above Detailed Description using the singular or plural number may also include the plural or singular number respectively.
